COMBINED PULVERIZER AND ROLLER.

SPECIFICATION forming part of Letters Patent No."753,953, dated March 8,1904.

Application filed June 24, 1903.

T0 at whom it may concern.-

Be it known that I, MALCOLM Gr. CAMERON, a citizen of the United States,residing at Thomas, in the county of J efferson and State of Alabamahaveinvented certain new and useful Improvements in a Combined Pulverizerand Roller, of which the following is a specification.

It is the object of my invention to provide a novel and improved clodcrusher and roller combined, which comprises a pulverizing-roll forbreaking or crushing up the clods of earth preparatory to planting whichis mounted in a suitable frame in advance of a smooth roll, so that boththe crushing and rolling can be performed at the same time and'in themost expeditious and satisfactory manner.

My invention consists in the construction and arrangement of partshereinafter set forth and described, and more particularly pointed outin the claims, reference being bad to the accompanying drawings, inwhich- Figure 1 is a side view of my combined pulverizing and rollingimplement. Fig. 2 is a top plan view which shows more clearly'theconstruction of the pulverizing-rolls. Fig. 3 is a detail view showingthe manner of loosely mounting the smooth roll in the frame. Fig. 4shows one of the special disks used to strengthen the pulverizing-rollsbetween their heads.

The same reference-letters refer to the same parts throughout.

According to my invention I mount pulverizing-rolls A upon a commonshaft B, which is rigidly mounted in the forward end of a frame C insuitable bearings therefor. A series of smooth rolls D are mounted on ashaft E, whose ends are provided with antifrictionrollers F, serving asbearing-boxes for the shaft, that enter vertically-disposed slots orguides G in the frame and permit of the free vertical movement of theserolls for the purposes hereinafter described.

A tongue H is pivotally secured to the front beam of the frame 0, towhich also a vertically-disposed plate I is rigidly bolted. This plate,which is inclined slightly to the rear, is provided on its forward facewith a series Serial No. 162,884. (No model.)

thereto in any desirable manner. To one of these hooks a doubletree K isattached. I provide a series of these hooks and dispose them in themanner shown for the purpose of utilizing the draft strain to adjust therelative pressures of the rolls A and D, and thus adapt the machine todifferent kinds of work, for it is evident that if the doubletree beattached to the highest hook it will exert the downward pull of thedraft on the rolls A to a greater extent than when the draft strain ison oneof the lower hooks, which is practically in line with the bearingsfor the rolls. This plate therefore acts after the fashion of a clevis,but with a much wider range of control. The freevertical movement of therolls D in their bearings in the frame permits the pressure exerted bythe pulverizing-rolls to be varied without the pressure exerted by thesmooth rolls being aflected thereby; otherwise if they were rigidlymounted in the frame the draft strain would act on the front rolls as afulcrum to lighten the pressure of the rear rolls, which is a result Idesire to avoid.

A weight or rock box Lis supported above the rolls on bent iron bars M,which are mounted on the axles B and E adjacent to the side bars of theframe.

It is of great importance in constructing pulverizing-rolls that theyshould crush or break the clods of earth and not simply press them intothe ground. With this object in view I preferably construct thepulverizingrolls A out of a number of transversely-disposed bars N,suitably spaced apart and connected at their ends to heads 0. 7Intermediate strengthening-disks P may be used, if desired, or the rollsmay be constructed in any suitable manner, since their construction andarrangement form no part of this particular invention as hereinafterclaimed. This bearingsurface constitutes about one-third of the face ofthe roll, and since it bears the entire weight of the roll it willthoroughly crush the clods,

but by reason of the interstices in its bearingface will not have atendency to force them into the ground.

A seat B may be attached to the weight-box or to the frame in anydesirable manner.

of hooks J, either integral therewith or bolted Having thus described myinvention, what I I00 scribed, a frame, pulverizing and smoothrollsjournaled therein, a Weight-box mounted on the journals of saidrolls, and means to increase the pressure on one of said rolls Withoutaffecting the pressure on the other.

3. In combination, a frame, crusher-rolls journaled therein, a smoothroll journaled in said frame, a Weight boX and a clevis cooperatingtherewith to vary the pressure upon one roll Without affecting theother.

4:. In combination, a frame, pulverizer and smooth rolls journaled insaid frame, means to Vary the pressure on said pulverizing-rolls Withoutaffecting said smooth roll and a weightboX mounted on the journals ofsaid rolls.

5. In combination, a main frame, adjustable clevis draft devices mountedthereon, crushing-rolls and smooth rolls mounted therein, anfi aweight-box mounted on the axes of said ro s.

6. In combination, a main frame, pulverizer and smooth rolls journaledtherein, a Weightloox mounted on the journals of said rolls, and a seatsecured to the said weight-box.

In testimony WhereofI affix my signature in presence of two Witnesses.
